The members 5 and 6 are magnet 17 through the coil 25 and between the ends or oles and 46 of the magnet and has on'elther side thereof, intermediate its ends, contact points47 and 48 adapted to contact with the points 49 and 50 on the reeds 37 and 38.

Projecting through the sides ofthe combination housing and magnet 17 are screws 87 and 88 having nuts 89 and 9O thereon. and being provided at their inner ends with nonconducting tips 51 and 52 adapted when the screws are moved inwardly and outwardly to'act as adjustments for the reeds 37 and 38. Also disposed on the top oft-he housing member 6 is a conventional ammeter 53 adapted to be connected with the wire 71 extending from the contact points 47 and 48 and also with the battery 72.

Disposed Within the casing is the customary primary coil 58 and secondary coil 59 having a third winding- 60 thereon.

The combination housing and magnet 17 isiprovided with a nonconducting top 61 secured thereon by means of screws 62 or any other suitable means. An aperaturc 63 is provided through the top 61 and a counter sunk portion 64 disposed therearound into which a glass 65 may be placed and secured by means of a name pla 66 secured to the top 61 by means of screws 67. The name plate 66 has an aperture 68 therein corresponding With the aperture 63 in the top (31. In this manner, it will be possible to view from the outside the contact points on the reeds 34, 37 and 38 to determine Whether or not they are sparking. A

The electrical operation of my improved device is more or less conventional and consists of applying alternating current voltage through the conductors 69 and 70 to a primary coil 58. Voltage is induced from the primary coil 58 to the third winding 60 so as'to create an induced current flowing through the conductor 76, coil25 and conductor 77 back into the winding 60. This current passing coil 25 will; in conjunction with, the magnet 17, cause'the vibration of the reed 34, so as to alternately make and break contact of thejpoints 47 and 48 with the points 49 and 50 on the reeds 37 and 38. The chargingcurrent flows from the secondary coil 59 through either the conductor 74 or 75 and the contact points "49 or 50 into the ammeter 53, through the conductor 71, and thence into the battery 72, and through the conductor 73 back into thesecondary 59., It is, of course, necessary that the reed 34 shall vibrate in a manner whereby substantially no sparking shall occur on the breaking of therontact of the points 47 and 48, with thepoints 49 and 50. The method of accomplishing'this result is Well known in the art, does not constitute a-pormade in the arrangement, combination and construction of the varioustparts of my improved device Without departing from the spirit of my invention and'it is my intention to cover by my claims such changes as may be reasonably included within the scope thereof.

Vhat I claim is:

1. A device of the class described, comprising a rectifier having a vibratory reed; means, including a magnet, for causing said reed to vibrate,'and a housing for said reed comprising said magnet on the sides thereof and cover members secured to the bottom and to the top of said magnet.

2. A device of the class described, comprising a rectifier having a vibratory reed, means, including a magnet, for causing said reed to vibrate, and a housing "for said reed comprising said magnet on the sides thereof and cover members secured to the bottom and to the top of said magnet, said top cover member having an aperture therein and a countersunk portion around said aperture, glass disposed in said countersunk portion, and a second cover disposed over said countersunk portion and having an aperture therein registering with said first aperture.

3. A device of the class described, vcomprising a rectified having a vibratory reed, a magnet and a coil member suspended by angle plates secured to the sides of said magnet, said reed being extended through said coil and having one end loosely disposed between the ;tree ends of said magnet and having contact points intermediate its ends Within said magnet and a strap-secured to said free ends of said magnet so that all the reeds and contact points thereon will be enclosed.

4. A device of the class described, comprising a rectifier having avibratory reed, a magnet and a coil member suspended on the inside of the magnet walls by angle plates secured to the sides of said magnet, said reed being extended through said coil and having one end disposed between the free ends of said magnet, a strap secured to the free ends of the magnet and a'pair of reeds disposed one on either side of said first reed and having contact points thereon adapted toalternately contact with contact points disposed on either side of said first reed intermediate ,its ends, all of said contact points being located Within said -magnet Walls and all of said reeds being enclosed by said magnet and said strap.
